Last year, advocates pushed to reallocate money from police departments into social services. This year, the City Council increased the NYPD's budget by $200 million — and the frontrunner for New York City mayor is a former NYPD officer. What's changed? 

"Many homeowners — black, white, other — agree that there should be police in the streets, and they are frustrated by the rise in crime, both minor and major," said Dr. Christina Greer, a political science professor. "But they also believe that police officers should not run through their communities with reckless abandon and make them less safe. So you can't be afraid of the cops AND the robbers. You have to make sure the policing that is in place is actually there to support a community, not make a community feel threatened."
